Ozonium root rot is classified as which type of disease?

1. Bacterial disease

2. Virus disease

3. Fungus disease

4. Parasite

The correct answer is: Fungus disease

Ozonium root rot is categorized as a fungus disease because it is primarily caused by the pathogenic fungus Ozonium spp. Fungal diseases typically affect root systems by invading plant tissues, leading to symptoms such as wilting, yellowing, and eventual plant decline or death. Understanding the nature of the pathogen is crucial in plant disease management, as fungal infections often require specific control measures, such as fungicides or alterations in cultural practices, to mitigate their impact. By correctly identifying Ozonium root rot as a fungus disease, it allows for targeted management strategies that are more likely to be effective in preventing the disease from affecting other plants.
